Inter-Speaker Variation in Spanish. An Experimental and Acoustic Preliminary Approach

Main factors that traditionally have been proved to influence the process of speaker identification are fundamental frequency (F0), vocalic formants, nasal energy distribution, and LTAS. The aim of this preliminary paper is to establish certain methodology in order to confirm the pertinence of these factors in Spanish. Based on a certain part of oral corpus AHUMADA, two successive procedures have been followed: first, an acoustic descriptive analysis of relevant parameters. Second, a perceptual test was designed to assess the role of these elements in the identification of speakers.
